    I'm used to seeing clouds of black crap on the front rotors, especially after a fresh pads or heavy use.

    Just pulled the rear wheels off the dually, and there's tons o' dust in there.

    Question is: should I be worried?

    Details: Rear disc, with 3/4 ton front calipers, and Express van rotors, as it's DRW. Pads are fresh, rotors are new, calipers are fresh rebuilts.

    I'm inclined to think the rotors may be a bit thicker than spec (lordie, I DO hope they're spec'd the same as the SRW varieties) and so this is normal.

    Oh, I've always been tweaking the adjustable prop valve, so I may have dragged the rears a bit playing with them =))
